倒F天线(IFA, Inverted-F antenna) 归类:如图1所示为一倒F天线(IFA, Inverted-F antenna)。这种天线似乎是线天线,但在对这种天线的辐射方式进行分析之后,就会发现它应该归类为孔径天线。 馈电:馈电在接地(Ground Plane)与IFA的上臂(Arm)之间。 上臂:IFA的上臂的长度大约是波长的四分之一。 短路:如图1所示的IFA...

Below is a quarter wave ground plane antenna I made for 23cm, 1296MHz which is made from off-cuts of household mains copper wire and a scrap BNC socket from the junk box. The one pictured below is for receiving ADS-B aircraft signals on 1090MHz, again using scrap copper, but this tim...
5.3 规模、成本和性能-Size, Cost and Performance 理想的天线体积无限小,成本为零,性能优异。在现实生活中,这是不可能的。因此,需要找到这些参数之间的折衷方案。通过将工作频率降低两倍,有效范围增加了一倍。因此,在设计射频应用程序时,选择在低频率下操作的原因之一往往是需要长距离操作。然而,大多数天线在低频时需...
A small printed antenna is described with a reduced ground-plane effect for ultrawideband (UWB) applications. The radiator and ground plane of the antenna are etched onto a piece of printed circuit board (PCB) with an overall size of 25mmtimes25 mmtimes1.5 mm. A notch is cut from the rad...
